HIMSELF AND HENRY COULTER, OF SAME PLAGE.

Letters Paten-t No. 107,598, lated September 20, 1870.

I, EDWARD CROFT, of Philadelphia, county of Philadelphia, State of Pensylvania, have invented aul Improved Fastening for Preserve-,Target which the following is a specification.

Nature and Object of the Invention.

M yiuveution consists of a bale or yoke hinged to' Description of thc Accompanying Drawing. Figure 1 is avertical section of the top of 'a fruitjar and cover, with my device for securing the latter 5 Figure 2, an exterior side view of g. 1; Figure 3, a perspective view of' vthe fastening device; vand Figure 4, an exterior view of the top oi' the jar.

Y r'en'eral Description. A represents the neck of a fruit-jar, on the edge of the mouth Aof which there is, in the present case, anA

annular rib adapted to an annular recess in the cover B, the said recess containing a packing-ring, a..

1t should be understood that my invention has no l relation to' any particular inode of adapting the cover to the jar, or to any specific arrangement of packing,

as my invention may be applied to many different styles of fruit-jars. .4

Round the neck of the jar is formed an annular re Vcess, c, g. 4, for receiving the wire ring D, on the opposite sides of which are formetlloops b b, and to the latter are connected the opposite endsV of the wire yoke or bale E, and to a loop, j, on the middle of the yoke, is loosely connected the upper end of alielical spring, G, the lower end ofthe latter being arranged to t freely over a central projection, m, of the cover B, as shown iu fig. 1.

The ring D is permanently secured in the recess e of the jar, the loops b b of the ring oecupyingpositions in recesses h h, formed near lthe mouth ofthe jar, and communicating with the recess e, as shown in tic'. 4.

bAfter the cover has been litted to the mouth ofthe jar, the yoke and its spring are first brought to the position shown in iig. 2, the lower end of the spring bearing against the edge of the projection m of the cover.

The yoke is then, elevated to the position shown by dotted lines in iig. 2, indoing which the spring is necessarily compressed, and, when elevated, continues to exert a pressure on the cover, and to maintain the packed joint perfectly tight, the spring haring a tendency to retain its upright position until by a slight eiort it can be turned down, so as to permit the removal of the cover.

` Claims.

l. A ball or yoke, E, hinged to the neck of' a fruitjar, so as to .turn over the cap of the same, in combination with a spring, G, for depressing the cover.

2. The combination of the said yoke and spring with the projection m of the cover.

3. The combination of `the wire ring D and its loops b b with the lannular recess e` and recesses h ot' the jar.

I n testimony whereof I liave signed my name to this specification in the'presence of two subscrib-v ing witnesses.
